Internet Atlas to NS2 is a continuation of Internet Atlas, which provides a geographically anchored representation of the physical Internet including (i) nodes (e.g., hosting facilities and data centers), (ii) conduits/links that connect these nodes, and (iii) relevant meta data (e.g., source provenance).

This tool adds the feature of extrapolating the generated map to a Network Simulator 2 topology and allows you to customize it by filtering the topology based on geo-coordinates. The customized map of network topology can be converted into a Network Simulator script that can then be run on an NS engine.
